Immediate ConsultationProduct Introduction
HXGN15-12 indoor AC metal-enclosed fixed high-voltage switchgear (hereinafter referred to as ring main unit) is a complete set of distribution device for 12KV three-phase AC 50Hz power supply system. It can be widely used in the construction and renovation of urban power grids, suitable for distribution systems in industrial and mining enterprises, high-rise buildings, residential communities, hospitals, schools, parks, etc., for receiving and distributing electrical energy. It is mainly used for ring network power supply and terminal power supply, and is also suitable for installation in portable substations.
Product Features
The cabinet body is of assembled structure, fully metal enclosed, with a protection level of IP3X; the main components inside the cabinet are vacuum load switches (pneumatic load switches), which can be used in conjunction with fuses, grounding switches, voltage transformers, and current transformers, or used separately to meet different operational requirements, breaking load current and short-circuit current, and closing short-circuit current.
